The 37-year-old actress has been in a relationship with the dark-haired beau for five years when they started dating in 2012, band although the couple have 15-month-old son Rocco together and have yet to tie the knot, she still refers to him as her spouse.

Speaking to ES magazine about her the 47-year-old actor, the brunette beauty said: "He's practically my husband, so calling him that is easier.

"The formality isn't a draw for me, but we'll do it one day. Once you have children, I just think, why not? It would be great if everyone in Australia could get married though. What's the hold up? Get with the programme, Australia."

And the Sydney-born star has revealed since giving birth to her child last year she feels a lot closer to her family, including her siblings Lucy, 44, Alice, 43, and George, 40.

The 'Bridesmaids' star explained: "I'm really close to them [her family], and they all have children, and having my own immediately made me want to spend more time all together - all those clichés."

Although Rose lives in London, she has admitted she often feels like an "alien" working around the capital.

She said: "I'm an Australian through and through. Even though I have been here for 10 years, I'm not a citizen, and I still wake up on some days and go, 'What am I doing here? I'm an alien.'"
